Title: Add multiselections to treelist control

I've added the ability to have multiple selections in a treelist control (if the style is enabled). The multiple selection mechanism attempts to behave like multiple selections in a listview. Control and Shift keys work generally as expected. However, selecting a parent does not select its children unless done explicitly.

There is no longer a **tl->selected_item** any longer. Instead, the selection(s) are determined strictly by the item state.

I realize this is a sizeable change, so I understand if pulling this in will require some serious consideration.
